1. Produto rematadoview

The Juniper EX2200-24P-4G is a high-performance 24-port 10/100/1000BASE-T Ethernet switch designed for enterprise access layer deployments. It features Power over Ethernet Plus (PoE+) capabilities on all 24 access ports, providing power to connected devices such as IP phones, wireless access points, and video surveillance cameras. Additionally, it includes four SFP (Small Form-Factor Pluggable) Gigabit Ethernet uplink ports for flexible network connectivity.

This switch is engineered to deliver reliable, secure, and energy-efficient network access, making it suitable for various business environments requiring robust connectivity and power delivery over Ethernet.

This image displays the front panel of the Juniper EX2200-24P-4G switch. It features 24 Gigabit Ethernet ports with PoE+ capabilities, arranged in two rows of twelve. To the right, there are four SFP (Small Form-Factor Pluggable) Gigabit Ethernet uplink ports, along with LED indicators for system status and port activity.

2. Configuración e instalación

2.1 Desembalaxe e inspección

• Carefully unpack the switch and its accessories from the shipping carton.
• Verifique que estean presentes todos os compoñentes listados na lista de embalaxe.
• Inspect the switch for any physical damage. If damage is found, contact your vendor immediately.

2.2 Montaxe en rack

The EX2200-24P-4G switch is designed for standard 19-inch rack mounting. Use the provided rack-mount brackets and screws to secure the switch in the rack. Ensure adequate ventilation space around the unit.

2.3 Conexión de alimentación

1. Connect the provided AC power cord to the power inlet on the rear panel of the switch.
2. Conecte o outro extremo do cable de alimentación a unha toma eléctrica conectada a terra.
3. Verify that the system status LED on the front panel illuminates, indicating power is supplied.

2.4 Initial Configuration (Console Access)

For initial configuration, connect a console cable (RJ-45 to DB-9 or USB-to-serial adapter) from your management workstation to the console port on the front panel of the switch. Use a terminal emulation program (e.g., PuTTY, Tera Term) with the following settings:

• Velocidade de transmisión: 9600
• Bits de datos: 8
• Paridade: Ningún
• Bits de parada: 1
• Control de fluxo: ningún

Once connected, you can access the command-line interface (CLI) to perform basic setup, including IP address assignment, user accounts, and network settings.

3. Instrucións de funcionamento

3.1 Conexión de dispositivos de rede

Connect Ethernet cables from your network devices (computers, servers, IP cameras, access points) to the RJ-45 ports (1-24) on the front panel of the switch. The switch automatically detects the speed and duplex mode of the connected device.

3.2 Power over Ethernet Plus (PoE+)

The EX2200-24P-4G supports PoE+ (802.3at) on all 24 access ports. When a PoE-compatible device is connected, the switch automatically detects its power requirements and supplies power over the Ethernet cable, eliminating the need for separate power adapters for these devices.

• Ensure the connected device is PoE/PoE+ compliant.
• Monitor the PoE status LEDs for each port to confirm power delivery.

3.3 SFP Uplink Ports

The four SFP ports (25-28) are used for high-speed uplink connections to other network devices such as core switches or routers. Insert compatible SFP transceivers (fiber or copper) into these slots and connect appropriate cables.

3.4 Indicadores LED

The front panel features various LEDs to indicate the operational status of the switch and its ports:

• LED SISTEMA: Indicates overall system status (e.g., green for normal operation, amber for fault).
• LED ALM: Indicates alarm conditions.
• LED PoE: Indicates PoE status.
• LED de porto: Each RJ-45 and SFP port has LEDs indicating link status and activity.

Refer to the official Juniper documentation for a detailed explanation of each LED state.

4. Mantemento

4.1 Limpeza

Regularly clean the exterior of the switch with a soft, dry, lint-free cloth. Do not use liquid or aerosol cleaners directly on the unit. Ensure ventilation openings are free from dust and obstructions.

4.2 Actualizacións de firmware

Comprobe periodicamente o soporte de Juniper Networks website for the latest firmware updates. Keeping the firmware up-to-date ensures optimal performance, security, and access to new features. Follow the instructions provided with the firmware update package carefully.

4.3 Consideracións ambientais

Ensure the switch operates within its specified environmental limits (temperature, humidity). Maintain proper airflow around the device to prevent overheating. Avoid placing the switch in direct sunlight or near heat sources.

5 Solución de problemas

5.1 Sen enerxía

• Verifique que o cable de alimentación estea conectado correctamente tanto ao interruptor como á toma de corrente.
• Comprobe a toma de corrente con outro dispositivo para asegurarse de que funciona.
• Asegúrese de que a fonte de alimentación (se é externa) estea conectada correctamente e funcione.

5.2 Sen ligazón no porto

• Check the Ethernet cable for damage and ensure it is securely plugged into both the switch port and the connected device.
• Comprobe que o dispositivo conectado estea acendido e funcione correctamente.
• Try a different port on the switch or a different Ethernet cable.
• Comprobe a configuración do porto no conmutador (por exemplo, velocidade, configuración dúplex).

5.3 O dispositivo PoE non recibe enerxía

• Ensure the connected device is PoE/PoE+ compliant.
• Comprobe o LED de estado de PoE para o porto específico.
• Verify that the switch's total PoE power budget is not exceeded.
• Tenta conectar o dispositivo a un porto PoE diferente.

5.4 Problemas de conectividade de rede

• Verifique a configuración do enderezo IP no conmutador e nos dispositivos conectados.
• Comproba se hai conflitos de enderezos IP na rede.
• Ensure proper routing is configured if devices are on different subnets.
• Consult the Juniper Networks documentation for advanced troubleshooting steps.
